Application of Single Phase Matrix Converter Topology in Uninterruptible Power Supply Circuit incorporating Unity Power Factor Control

Abstract

This paper presents the SPMC topology that will operate as an Uninterruptible Power Supply Circuit (UPS) incorporating Unity Power Factor Control. A single circuit is developed that performs both the rectifier and inverter operation may also incorporate active power filter operation. Commutation strategies are also implemented with reduction in spikes, a common phenomenon in matrix converter topologies. Results of simulations and selected experimental results are presented to verify that the proposed technique is feasible.
